NSW Labor has issued issued a bipartisan call to NSW Premier Gladys Berejiklian to hold another drug summit along the historic one held in 1999 by then-Premier Bob Carr.

The call followed the release of national figures showing drug use has significantly changed since the 1999 Drug Summit at NSW Parliament.

In 2015, NSW Labor leader Luke Foley and Mr Walt Secord, the Shadow Health Minister, pledged the next Labor Government would hold a drug summit.

Since then, members including Jo Haylen, the Member for Summer Hill, have been calling for a summit to be held in this term of Government.

Quotes attributable to Jo Haylen MP, Member for Summer Hill

"Politicians are not the experts when it comes to dealing with illicit drugs. We need to listen to the medical experts, front line workers, legal experts and drug consumers themselves to get these policy settings right. 

"The 1999 Summit was a landmark event that delivered bold policies that have worked, including the Medically Supervised Injecting Centre in Kings Cross. 

"It's time to be brave again and to trial new approaches. A Summit is clearly the best way to have that conversation."
